The Big Lebowski? It's a cult comedy hit but I'm just not seein it, other than a few amusing lines (the rug really tied the room together).

I've seen There Will Be Blood and Fargo. I wish I could have a more in-depth discussion about them but it's been a long time since I've seen them and I didn't rank them higher than 7/10 so not a great recollection of what happened. The dark, slow atmosphere of There Will Be Blood reminded me of No Country For Old Men except the latter movie is about 100 times better.
